- Q: i dont wanna buy a solar panel becuase its too exspensive, i dont want use technical stuff i want to use every day materiels, but i need to know asap plzzzz.
- Make okorder
- Q: Are there any safety concerns with solar panels?
- There are a few safety concerns associated with solar panels, but they are relatively minimal and manageable. The main concerns include the risk of electrical shock during installation or maintenance if proper precautions aren't followed, fire hazards due to faulty wiring or improper installation, and potential damage from extreme weather conditions. However, with proper installation, regular maintenance, and adherence to safety guidelines, these risks can be significantly mitigated, ensuring the safe use of solar panels.
- Q: What is the difference between Photovoltaic Panels and Solar Panels?
- Photovoltaic is a type of solar panel that produces electricity from sunlight, usually converting about 5% - 22% of the energy received from the sun into usuable energy. There are different types including those grown in a lab, silicone, and glass. Another type of solar panel is solar thermal which convert sunlight into heat. This is usually ran into some sort of system that heats water or a mixture w/ glycol in colder regions. This hot water can be used for showers, etc, or heating the home. You get much more bang for your buck with solar thermal.
- Q: How about using Solar Panals to provide the electrical power to separate the H2 from the O? H2 would be fed into the engines carburator like a gas/air mixture ratio, but H2/air mixture ratio instead. How would you control the exact measurements?
- H2 has more energy per weight – but requires twice the volume of fuel. It is unsafe to transport as a liquid or gas (usually in a carrier medium of some sort) Solar panels are expensive (low output per $) and expire after some use. They are dirty and energy inefficient to make too. However: hydroelectric, wind, and sea technologies may offer some improvements in costs with oil prices as high as they are.
- Q: I'm making a model of a solar photovoltaic tower for a school project. I need a way to store energy, and we thought about using capacitors (mainly because of our somewhat limited funding). The tower will have a small photovoltaic panel (around the size of a laptop keyboard with number pad) and some (around 50) quot;heliostats(just the mirrors, no moving parts). What kind of capacitors should i use? and would a capacitor bank be better? i am getting confused with all those uF, pF and can't see the difference.Thanx in advance

- Q: Our school is in the process of being built, but they have no plans to include any environmental benefits. I was wondering how to get a grant for solar panels (at least) or who I can talk to in order to get a grant.
- Call the Architect and ask what the heck he should have put solar panels into the plans for the building. Demand Results, If no results call your local newspaper
- Q: why don't we take a cue from mother nature and make our soar panels like trees? thousands of leaves or needle (like a pine tree) instead of one big flat panel? I mean it seems to work pretty good for all the plants i see why would it not work for us. It would be aesthetically pleasing and with the right engineering wouldn't it make them not have to worry about tracking the sun? i already have some ideas about the process of making them just no available labratory.
- Because we and the trees are trying to solve a different problem. We want electricity, a tree wants light (and some heat) for photosynthesis. In getting the electricity we use Silicon for solar panels. (Sometimes Gallium Arsenide). And we exploit the same thing in Silicon that allows them to be computer chips. The fact that they conduct differently when voltage is applied. But for a solar panel that is done essentially in reverse. We GET a voltage difference (electricity) from shoving energy through it. Look up junction bias on google or yahoo for explanation. But the DESIGN problem is: You have to couple these panels together the right way - according to their bias. You can't string them up willy nilly. There is a pattern. And when one breaks in this pattern. (I mean when the actual panel cracks, which they do easily as they are brittle). It can change the overall bias. This can make even be worse than if it was removed, it can actually fight against the working ones. The efficiency is there in arranging them like a tree, but the practicality of maintenance would be daunting.
- Q: I was thinking about getting some GE Solar Panels and on there website that I am on, I didn't really see a price. can anybody give me maybe an estimate on how much each one would cost? thanks
- Retail, between $5 to $6 /watt.
- Q: Can solar panels be installed on a shaded roof?
- Yes, solar panels can be installed on a shaded roof. However, it is important to note that shade can significantly reduce the overall efficiency and performance of solar panels. Therefore, it is advisable to assess the extent and duration of shade on the roof before installing solar panels to ensure optimal energy generation. Additionally, alternative solutions such as ground-mounted systems or removing nearby obstructions may be considered to maximize solar panel efficiency.
- Q: I am learning all about heat radiation in Physics. There is a question I am doing about Solar panels. It asks, why do glass covers improve the efficient of solar panels? I dont really understand. How do they?? thanks :D x
- the glass has an anti-reflective coating that helps the panel absorb more light (to convert to electricity) thant it would if the glass were not there. the other purpose of glass is to retain heat and strengthen the panel
